HAZ and BAZ were calculated according to World Health Organization growth standards and references. Multivariable logistic regression models were used to assess associations between HAZ, BAZ, and urolithiasis after adjustment for sex, ethnicity, age, and study center. Restricted cubic spline models were used to examine dose\u2013response and nonlinear relationships, and subgroup analyses were performed by study center, sex, ethnicity, age group, and nutritional status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Children with urolithiasis had lower HAZ and BAZ than controls (HAZ: \u22120.79 (\u22121.74, 0.24) compared with 0.57 (\u22120.29, 1.41); BAZ: \u22120.25 (\u22121.19, 0.77) compared with 0.36 (\u22120.61, 1.43); both\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001).
